Boomtschak - one of the most powerful entirely analog drum voices in Eurorack. As sound sources it uses an oscillator with waveshaper, a filtered noise or the mix of both. Not less than three flexible envelope generators are included, for pitch bending and the amplifiers. The resonant multi-mode filter can be fed with external audio signals instead the noise generator. The module's frequency range is huge, thus allowing for using it as a synthesizer voice.

This passive bus board's main feature are the noise filtering capacitors located at three locations of the board. They reduce noise and bleedthru between modules and provide for clean signals. 17 connectors for modules are more than competitors' busboards offer.

The Missing Link by Jabrudian Industries is a handy small device which converts OSC data into MIDI. In practical use this means that you can control your synthesizers wireless via an iPad or similar touch devices with Apps like TouchOSC.

Besides true stereo wave shaping the digital Shapes module offers the possiblity to scan one of 16 interpolated wavetables using audio and CV inputs. To do this you can induct any input signal, from a sine oscillator to an entire stereo sum, whereupon the grade of erosion or destruction rises with the complexity of the audio material.

The first Eurorack module by Snazzy FX is a dual Chaos Oscillator. Unlike normal VCOs it is not intended to produce tonal results but for creating chaotic, wild and unpredictable sounds, modulations and gates.

This digital module is specialized in one effect only: thick, juicy and fantastic chorus, thanks to automatic routing ieven in true stereo. It offers internal modulation, feedback and has two different chorus modes whose slightly different sound you might already know from the Audio Damage plug-ins Fluid and Dimensions.
The module's DSP works with proper 24Bit and 48kHz and also the mechanical quality is rock-solid.

This MIDI interface definitely stands out because monophonic conversion of MIDI notes (from MIDI In or USB) into CV and gate as well as MIDI Clock to analog clock is one function only. As the USB port in this module can send data too, you might as well convert MIDI data from the DIN socket to USB MIDI (or the other way round) and convert analog clock into MIDI Clock.
Let's read the sentence one again: use your modular system for generating a MIDI master Clock and synchronise for instance your computer to your modular!!!

Digital oscillator with a huge frequency range and the possibility to read your own waveforms in .wav format from a SD card in addition to the internal wave forms. Ultra-stable tracking due to it's digital core make it perfect for FM sounds. Phase and symmetry of the waveforms can be voltage controlled.

Although the Proton makes for a pretty nice delay its main focus of attention is a type of physical modeling called Karplus-Strong synthesis. It creates percussive sounds which resemple a plucked nylon strong but Proton is able to twist them in a strong way by filtering and by adding noise impulses.

Just like his small brother, the Echo, also the DLY is built around the same semi-digital bucket-brigade IC (PT2399) and thus has a similar character. But it has been improved in a few points, is more useful as a delay and has a dry/wet function now.
Doesn't cost much, sounds metalllic and really good, unless you reach the IC's extreme ranges where interesting artifacts happen. :)

The licensed Eurorack version of the programmable mini synthesizer Patchblocks allows the user to to program and to customize the module's behaviour via a intuitive software editor.
Some of the functions the module is capable of are VCO, clock divider, envelope and random generators, counter, shepard generator, sequencer, MIDI converter and many more. It is even possible to use it as a sample player (e.g. for drums) or as an effect.

Dub Junior's Mk2 version also is based in the delay algorithms used in the Audio Damage Plug In Dubstation and the old DubJr module but it has been clearly enhanced and improved regarding as well the features as the mechanical quality. It is a delay module with clock synchronization and tap-tempo, 24Bit/48kHz quality, two modes, two timpbres and external feedback loop. A worthy successor to the best-selling, venerable DubJr.

Unique wavetable VCO with 2 independent waveform outputs. What sets the E350 apart from previous wavetable oscillators is the voltage-controlled two-dimensional morphing. Sound is really good and clear.

As a clone of the open source project CV PAL by Mutable Instruments the Midi 2 CV is in first line fast as lightning, at least with certain computer operating systems. It offers various modes of operation, a range of four octaves and a resolution of less than 2 mV. It connects and is supplied with power via USB only.

All modules from Mungo's Zero series offer a Zoom function to operate all potentiometers (parameter controls and attenuators) with coarse, normal or fine resolution. This is especially super useful for oscillator frequencies and delay times. The Zoom module enables this function.
